10.95 Mavericks User Looking For a Solid Email Program for MS Outlook.

[anodecathode]

Mac Mail decided to bow out with the latest Microsoft 365 Outlook upgrade last year so I had been using a browser to access mail. Now it's slowing down significantly making it completely unusable.

Are there any email app suggestions that work with Mavericks & the latest Outlook upgrade? I'm still not ready to trade in my trusty TDM-HD6.

I have no problem running Apple Mail and MS Outlook together on my work laptop. What it is exactly that is not working?

With that said, latest Office 365 requires macOS 12 or later, so it is that which you should run on web browser.

Hey Jfreak, Microsoft discontinued support for basic auth with Microsoft 365 services starting sometime around June 2023. So Mac Mail 7.3 (Mavericks 10.95) stopped connecting to MS mail servers. From what I've read I need to find a mail app that supports OAuth. (if it exists) Currently the Firefox browser seems to work as a webmail app but it's starting to slow down a bit.

Here are a few links about it:

I was going to suggest Thunderbird but I see it only goes back to 10.12.

Well this here still is the ultimate problem. Your system (sig) is too old for it.

Thanks for explanation, so what you need is another mail application as MS won't work for you either.
